Iran preparing internal version of Internet

The Iranian government, determined to limit Western influence and defend itself against cyberattacks, appears to have laid the technical foundations for a national online network that would be detached from the Internet and permit tighter control over the flow of information.

The concept of a self-contained network has been reverberating within Iran for almost a decade and has often been treated with skepticism, given the significant investment in infrastructure and security that would be required. But Iranian officials and outside experts say that development of the network has accelerated following cyberattacks aimed at the country’s nuclear program.

Last month, Iran’s communications and information technology minister unveiled a plan to take key government agencies and military outfits offline and onto the new network by the end of September. U.S. security researchers say they are for the first time seeing evidence of an operational network that is consistent with Iran’s publicly stated plans.

The researchers, working under the auspices of the University of Pennsylvania’s Center for Global Communications Studies, say in a report to be released this week that they have found functional versions of the sites of government ministries, universities and businesses on the network. They also found evidence of an already operational filtering capability.
